Several major meta-analyses have concluded that exposure to environmental tobacco smoke (ETS) increases the risk of coronary heart disease (CHD) by about 25% among never smokers. However, these reviews have excluded a large portion of the epidemiologic evidence on questionable grounds and have been inconsistent in the selection of the results that are included.
We conducted an updated meta-analysis and critique of the evidence on ETS exposure and its relationship to death from CHD among never smokers. Our focus is on the U.S. cohort studies, which provide the vast majority of the available evidence. ETS exposure is assessed in terms of spousal smoking, self-reported estimates, and personal monitoring. The epidemiologic results are summarized by means of overall relative risks and dose-response relationships. The methodological issues of publication bias, exposure misclassification, and confounding are discussed.
Several large studies indicate that spousal smoking history is a valid measure of relative exposure to ETS, particularly for females. Personal monitoring of nonsmokers indicates that their average ETS exposure from a smoking spouse is equivalent in terms of nicotine exposure to smoking less than 0.1 cigarettes per day.
When all relevant studies are included in the meta-analysis and results are appropriately combined, current or ever exposure to ETS, as approximated by spousal smoking, is associated with roughly a 5% increased risk of death from CHD in never smokers. Furthermore, there is no dose-response relationship and no elevated risk associated with the highest level of ETS exposure in males or females. An objective assessment of the available epidemiologic evidence indicates that the association of ETS with CHD death in U.S. never smokers is very weak. Previous assessments appear to have overestimated the strength of the association.

Here's a study that we will never hear about in the MSM
PUFF
science would never allow agenda driven results.
Nonsense. Second hand smoke went away 20 years ago. The only way you can get second hand smoke is to hang out outside with the smokers.
Second hand smoke kills. I know a guy who had a cousin who's best friend played guitar for a band that played in night clubs. He never smoked a cigarette in his entire life. He died from second hand smoke when he was just 24 years old.
Or at least, that's the way the empirical data goes.
Or even better yet: A doctor said second hand smoke kills. Therefore, we must ban smoking in restaurants. Whose opinion matters more here, the restaurant owner's or the doctor's?
Maybe not - but it is excellent news against such idiots as Stanton Glantz and company who have tried to claim the opposite.
Wait, I've got another one!
It's for the children. When I go into restaurants and see the little babies in the cloud of smoke it just ... ((sniffle)) ... breaks my heart.
If I had it my way, people wouldn't be allowed to smoke in their homes if they've got the ... ((sniffle)) ... little babies in the homes.
((sniffle ... sniffle))
I knew a guy who smoked one cigarette after another, he would throw one down, stomp it out and light another, smoke it, throw it down, stomp it and light another. He finaly died of cancer of the shoe.
Be that as it may, this is still a public health issue. Nay, public health crisis. May I suggest an additional sin tax be placed on cigarettes and cigars and chewing tobacco to help pay for all the second-hand smoke lung cancer patients filling up the hospitals ...
Lay off my chew - no one has died from second hand spit.
LOL ... he probably also was buried in pauper's field from all the littering fines he had to pay.
Need an explanation?
That's as irrelevant as the rest of my arguments when you're talking about making money for the government!
Trying telling a city council that.

Thanks for the post!

We had two cockroaches die recently in a local nightclub from it:)

God rest his sole.
